Nice looking design. Congrats! The ONLY thing I would have done differently would be to move the controls up slightly (about 2 inches or so) so that there is more space to rest your palms when playing. The artwork would need some adjusting, I know. But it would prevent fatigue for the players in the long run. It looks a bit empty on the top of the panel and the controls seem off balance as a result. The Xtension arcade below is a good example of how there is slightly more space below the controls.
